Questions asked by users might not always be phrased in the clearest way.
Given below are two statements, one is labelled as Assertion (a) and the other is labelled as Reason (r). assertion (a): a mixture containing two enantiomers in equal proportions will have zero optical rotation. reason (r): The process of conversion of enantiomer into a racemic mixture is known as racemisation. in the light of above statements, choose the most appropriate answer from
Accepted Answer
Both Assertion (A) and Reason (R) are correct, and Reason (R) is the correct explanation for Assertion (A).
Here's why:
Assertion (A): A mixture containing two enantiomers in equal proportions is called a racemic mixture. Enantiomers rotate plane-polarized light in equal but opposite directions. In a racemic mixture, the rotations cancel out, resulting in zero optical rotation.
Reason (R): Racemization is the process of converting an enantiomer (a single stereoisomer) into a racemic mixture, containing equal amounts of both enantiomers. This often occurs through chemical reactions or by heating.
